3 essential tips for a successful boiler installation


Replacing a boiler is a big project – and an expensive one. A new boiler installation requires careful thought and planning. It’s no surprise that many don’t know where to start.

There are several key factors that affect the success of a boiler installation. This blog looks at our top tips for success.


1. Choose the right type of boiler


There are several different boilers on the market. Each one has its pros and cons.

Finding and selecting the correct boiler for your home has a lot to do with the size and type of your home, along with the number of people living there.

Combination boilers (or combi boilers) are a popular choice these days, but they aren’t the right choice for every home. Many elements need consideration.

So, it’s important to take time to make the correct choice. No one wants to install an expensive boiler, only to find that they’ve chosen the wrong type.

We look at the three most common boiler types and the benefits (and disadvantages) of each:


The combination boiler


Combi-boilers (or combination boilers) are a popular choice. They produce hot water as and when it’s needed – with no need to plan and wait for the water to heat.

And who likes deciding to have a bath, only to find that the water is tepid? With a combination boiler, hot water is ready when you want it.

Unlike other boilers, hot water doesn’t go to waste. It’s only used as and when required.

Another benefit of the combination boiler is that it takes up little space. A combination boiler doesn’t require a tank to be stored in a cupboard or attic.

This is a huge benefit in smaller properties and new homes, where space is a precious commodity.

A combination boiler installation is best suited to homes that:

  • Have very few household residents
  • Are smaller than average (such as apartments and new builds)
  • Don’t need hot water in different rooms at the same time
  • Have little or no attic space.

Another advantage of the combination boiler is that its components are housed on the inside of the boiler – making it compact and neat.

The downside of a combi boiler is that they aren’t designed to produce hot water for more than one person performing various tasks in different parts of the house.


The system boiler


Just like the combination boiler, the system boiler doesn’t require loft space to house a water tank. A system boiler tank is usually housed in a cupboard upstairs of a cupboard in an apartment hallway.

And components of a system boiler are often contained within the boiler – again, just like the combi boiler.

The biggest difference between the system and a combination boiler is that a system boiler supplies hot water to different parts of the house at the same time.

A system boiler installation is ideal for homes that:

  • Don’t have much space
    Have multiple bathrooms
    Contain no attic space
    Include multiple bathrooms
    Need a lot of hot water simultaneously.

The disadvantages of a system boiler are that heat is lost from the water cylinder. There is no hot water on tap. You must wait for the hot water to heat up again, once the hot water has gone.


The conventional boiler


The conventional boiler is a good choice for those with a larger property and a large number of occupants. Big volumes of water are heated and stored in a tank.

A conventional boiler installation is a sensible choice for the following types of properties:

  • Bigger properties with free loft space
  • Homes that have a higher demand for hot water
  • Properties that have two or more bathrooms.

System boilers don’t heat on demand, which is a disadvantage. When the hot water runs out, it needs time to heat again.


2. Choose the right size of boiler



It’s important to select the correct boiler size for your home.

There are two key things to consider when picking the best size boiler for your home. These are:


a) The physical size of the boiler you need

Always ask yourself the question – Where are you putting the boiler and what space is available? Take measurements of your space for the boiler and the tanks you need as part of the boiler installation.

b) The capabilities of the boiler for heating and hot water

Each boiler installation suits different households with different needs. Therefore, consider how much hot water you need when selecting the size for your boiler installation.


3. Choose the right boiler installation company



It’s never a good idea to replace a boiler yourself. A boiler installation is a job to leave for the professionals.
